Physical black holes: spacetime and matter near trapping surfaces
Swayamsiddha Maharana, Rama Vadapalli
Within a semiclassical framework, we investigate spherically symmetric solutions of the Einstein equations that (i) develop a trapped region within a finite time as measured by dis…
Padé metrics for black hole perturbations and light rings
Swayamsiddha Maharana, Fil Simovic, Ioannis Soranidis +1
Most distinguishing features of black holes and their mimickers are concentrated near the horizon. In contrast, astrophysical observations and theoretical considerations primarily…
The Hawking temperature of dynamical black holes via conformal transformations
Pravin Kumar Dahal, Swayamsiddha Maharana
In this second part of our two-series on extracting the Hawking temperature of dynamical black holes, we focus into spacetimes that are conformal transformations of static spacetim…
Models of cosmological black holes
Pravin K. Dahal, Swayamsiddha Maharana, Fil Simovic +2
We study various aspects of modeling astrophysical black holes using the recently introduced semiclassical formalism of physical black holes (PBHs). This approach is based on the m…
Horizon-bound objects: Kerr--Vaidya solutions
Pravin K. Dahal, Swayamsiddha Maharana, Fil Simovic +1
Kerr-Vaidya metrics are the simplest dynamical axially-symmetric solutions, all of which violate the null energy condition and thus are consistent with the formation of a trapped r…
Semiclassical corrections to the photon orbits of a non-rotating black hole
Swayamsiddha Maharana, Arundhati Dasgupta
In this brief article we discuss the corrections to the photon orbits of a non-rotating black hole due to semiclassical fluctuations of the metric. It is found that the photon orbi…
